Detailed explanation-1: -A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species, however, outweighs this disadvantage.

Detailed explanation-2: -since, complex body structure need time and energy both to produce the new individual by sexual mode of reproduction, so it is slow .

Detailed explanation-3: -Although sexual populations may evolve faster than asexual ones, it is still true that sexual individuals reproduce more slowly than asexual individuals; asexuality, once it has arisen, will tend to take over sexual groups.

Detailed explanation-4: -Sexual reproduction occurs in many eukaryotic organisms but has the disadvantage of being a slower form of reproduction. The advantage of this form of reproduction is that genetic variation is introduced, which has a selective advantage in environments that may change.
